Okay, this is actually going back a few months (it was posted on here), but I've had a lot of fish to fry since buying my house. Now I'm ready to turn my attention back to the spa. It's a mid-90's model Cal Spa. This manual looks to be a close match: http://www.calspas.com/manuals/download... rtable.pdf It is equipped with jets, but no bubbles. On to my situation: Note: I'm an absolute noob when it comes to both spas and electricity. Back in the fall, I used the spa for the first time. It was lovely. The next night, it wouldn't heat beyond lukewarm. The filter was clean. I had continued to let it run to see if it would warm up, and when I stuck my fingers in a while later I felt a mild shock ( " title="Shocked" /> ), enough to feel faint tingling up to the elbow for a couple minutes. Now, when this happened I was standing barefoot on a stepping stone on the lawn and reaching in (should that still be a problem?). Is the reason I wasn't shocked before using the tub perhaps because I was getting in from my wooden deck, thus not completing a circuit? Anyway, the pack has a GFI. Should it have tripped, or is it possible my shock was below the trigger threshold? I've only traced the electrical issue as far as the pump. There is current in the water whether the pump is running or not, but if i unplug the pump from the pack, then the current disappears (I'm testing this with a simple beeping tester w/o readings). The breaker can be on, the light can be on, but only if the pump is connected is there current in the water. Also, the pump is working (it circulates through the system, jets blow, etc.). So we have two issues here, possibly related? Water that barely heats at all now, and a pump that has (I'm guessing) a short. I would love it if someone could help me out here.

When you pull the pump you also stop the heater by opening the pressure/flow switch. Since there is no part of the motor that touches the water it seems more likely that the culprit would be in the heater circuit (either the pressure switch or the heater element itself) which could also explain your lack of heat.

Your GFI should be tripping. First step is to figure out why it's not. Then move on to the spa. If you're completely new to electrical work I'd suggest calling out an electrician to get the GFI sorted out and seeing if he'll help you diagnose the spa while he's there.

Thanks very much. I figured this would involve an electrician at some point, but I wanted to gain some knowledge before blindly jumping into that.

What you say about the pump/heater relationship makes sense, but should this still be the case when the pump is not operating (but plugged in)? I'm just making sure on that point. Thanks again.

Hmmm. Maybe your motor is sending juice back through the neutral into the rest of the components? In any event, power going to ground without the GFI cutting off is a bad state of affairs. I'd be hesitant to touch it myself without an electrician. Tracking it down will involve putting yourself right in harm's way so let the guy with the insulated tools take care of it and peek over his shoulder to learn what you can.

Sounds like a plan. Thanks again.
